    • Oil pressure rising when you bring the prop to feather

    • A accumulator failure not limiting a feathered and stopped prop from unfeathering without cranking the engine

    • Not being able to get the prop to feather even though the props aren't on the stop lock

      @Buzz I haven't looked into all of the details yet, but I believe all three of the points you mention are unrelated to the new propeller governor and fuel-topping governor behavior.

      • The first should just be a constant in the engine.cfg, which I believe was only set incorrectly by accident in one of my aircraft (Baron Professional?) I'll check my changelogs, but it should be fixed now.

      • I'm not sure exactly what the real world behavior is that you're describing here, but the only type of governor failure that I model in my aircraft is failure to achieve maximum RPM.

      • Assuming you're talking about when shutting down an engine, this could be fixed, and I've looked into it. My propeller simulation is where I fight with the underlying simulation harder than anywhere else, so progress is hard won. I might have an elegant solution to this that I will try before my round of summer updates, but I haven't made any promises in case it gets ugly.

        @Black-Square

        On #2 I meant an accumulator failure.. It was a slip on my part. I had reported this to you a few months ago. I edited my OP to correct my mistake.

        On #3, when I am demonstrating procedures for OEI, sometimes I can't get the prop to fully feather and I have to dive to get the inop engine RPM well above 1500 rpm and then quickly pull to feather detent. It's never that specific to get the prop to feather in the Baron.
